This thread has quickly grown and I haven't got time to go trough all the posts now.
Just wanna share my opinion with you.
Old MBPR has been designed in a way that allows you to open the bottom cover and clean all cooling components off dust easily. Even better, you can remove the cooling assembly and replace thermal paste on the CPU without voiding warranty.
The new MBP (I've looked at the 2018 models only as I've fancied purchasing one) were intentionally designed to prevent you keep the warranty if you want to detach CPU from cooler in order to reapply thermal paste on it. I was sad to see that.
My first thought was to take the new MBP to Apple Store for a cleaning and thermal paste job but that idea soon faded out as I have not been particularly happy with the quality of work that they did on my 2013 MBPR back in 2015 when I've had it in for warranty repair.
All in all I was really hooked in to buying the new 2018 MPB.
Then I KP problems started and I gave myself some time to see the real fix but it never surfaced.
I thought that Mac Mini would come in with T3 and free of the KPs - it did not happened.
The new "new" MBP came in and I just do not trust Apple my $4k for a laptop.
For what I do a Hackintosh will provide perfect firepower and upgradeability in desktop form factor for next 5 years to come. And I'll keep using my 2013 13" MBPR as a daily light work runner.
Apple has disappointed me in all the fields they could pull a disappointment at.
MBP Keyboards, MBP poor thermal solutions, T2 Kernel Panic, iMac Core i7 thermal solution, overall price is insane in EU...
I would remove the KP from the list of disappointments if Apple would have released a statement about the problem. They are acting dumb about it. You can call Apple and they will preach for hours about third party apps that are causing problems but they know it is all their problem. I've asked many times if they can prove that Autodesk Fusion 360 runs on the machine I wanna buy and it was impossible to set up in store test. Why is that not possible for a 4k machine?
I am not buying any Mac products until they sort this saga out.
So glad that someone is pushing this case. Poor Steve once said "We just can't ship junk"
